Trying to send a very simple request (see below) against my dev HubSpot instance to validate a POC for automating various actions through an orchestration tool like [Make.com](http://Make.com).  
\*\*Note, values are replaced with dummy’s below to protect sensitivity.

```lia-code-sample
{
 "emailId": xxxxxx,
 "message": {
 "to": "test@gmail.com",
 "from": "test@gmail.com"
 }
}

```

Getting this behemoth of an error… was anybody else able to debug this?
